Covering face

Picture:STOMP
This man was covering his face when he noticed someone taking a photo of him sitting on a priority sit on the MRT. Although he was sitting sitting on a priority seat, I think it is all right as long as he gives up his seat to someone who needs it more when he/she is there, instead of pretending to sleep, read, or playing handheld games. What do you think?
